60 THE STORY OF THE EARTH. 



cal Map. In one of his writings Dr. Lister 



:S a drawing of a small fossil, a Belemnite, 

 and states correctly, that it is found in all the 

 cliffs along the Yorkshire wolds, for a distance of 

 more than ioo miles, by Speeton, Londesbfo' and 

 Caistor, but always in a red ferruginous earth 

 [now known as the Hunstanton Limestone]. 



Mr. John Strachey in 17 19 laid before the 

 Royal Society evidence that the upturned and 

 led edges of the Coal Strata in the Somerset- 

 shire Coal Basin were covered by nearly hori- 

 zontal beds of the Red Marl, Lias, and Oolite. 



The Rev. John Holloway in 1723 described to 

 the Royal Society the parallelism of the Chalk 

 of the Gog-MagOg and Chiltern Hills, the Sand 

 Hills of Wobiirn, and the (/lay country drained 

 by the Lam, Ouse, Nen, and Isis. 



The Rev. John Mitchell in 1760 stated to the 

 Royal Society that "we ought to meet with the 

 same kinds of earths, stones and minerals appear- 

 ing at the surface in long narrow strips, and lying- 

 parallel to the greatest rise of any long ridges of 



mountains, and in tact we find them [thus ex- 

 posed], M The ndge m England which influences 

 the direction of the strata is said to run first 



north to south, and then from north-east to 

 south-west Travelling between the Chalk hills 

 of Cambridgeshire and the Coal of Nottingham 

 and Yorkshire, he observed the succession of the
